EATON C441 Series Motor Protection Relays
Eaton C441 Series motor protection relays are ideal for use as configurable protection units for a motor and associated circuits. They protect the devices from overcurrent, undercurrent & overvoltage conditions. These relays are generally used in industrial applications to protect circuits in p...umps, fans, conveyors & other equipment. They have a bright LED display and an intuitive user interface for easy configuration and troubleshooting of systems when required. These compact devices offer all motor protection & diagnostic functions needed to efficiently & effectively manage the system, irrespective of high line conditions & poor power quality.Read more

Working Mechanism
- Eaton C441 Series motor protection relays continuously monitor the electrical parameters like current, voltage & phase balance in a circuit.
- The relays trip on detecting a fault condition and open the electrical contacts to interrupt the power supply to the circuit & protect it from damage.
- After the relay is tripped, it displays a fault code or indication on the front display panel or through a set of status contacts, helping technicians to diagnose the cause of the fault and correct the issue.
- After the fault is cleared and the relay is reset, the relay again restores power to the circuit for normal operation.
Features
- Eaton C441 Series motor protection relays calculate power and monitor motor performance, load performance & energy consumption for system critical loads & pump loads.
- The monitoring capabilities include average current & phase RMS, average voltage & phase RMS, motor power (kW), power factor, frequency, thermal capacity, run hours, ground fault current, current / voltage unbalance percentage and the time before restarting.
- They further feature programmable reset / backspin timers, a lockable user interface, scaled current readings, individual trip delays and communication protocols like Modbus, DeviceNet & PROFIBUS.
- These relays have IP20 recessed terminals for safe connections and an LED display that remains bright even in low temperatures.
- Their displays have an enclosed assembly for enhanced safety. Selected models can also be connected to a remote display.
Compatible Accessories
- Eaton C441 Ethernet Communication Adapters: These devices fit onto these relays for connecting them to a computer using ethernet and allow remote management, monitoring & controlling of electrical parameters.
Standards and Approvals
- RoHS
- CE
- NEMA
- CSA
- EN 60947-4-1
- cULus
